METHOD AND APPARATUS FOR CALCULATING DATA

摘要

A data calculation method comprises: a step of acquiring a difference value between an inputted first data and a pre-saved second data; a step of determining a third data acquiring method corresponding to a calculation result of the first data based on the acquired difference value; and a step of performing a calculation procedure based on the pre-determined method by using at least one calculator. According to the present invention, it is possible to reduce an amount of information, saved in a lookup table, and the number of logic gates′ switching, caused by performing a multiplication calculation.
